1 Claim.

(Granted under the amended April 30,

The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to us of any royalty thereon.

The subject of this invention is a turret mounting intended for use on armored vehicles and the like.

The main objects of the invention are the provision of a mounting, which, while efiective, will occupy but little space within the turret; which will support the weight of the turret and also take lateral thrust, which is quickly and easily mounted, and which provides a simple and cheap construction.

With the foregoing and the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a fragmentary sectional view of a turret constructed in accordance with the invention.

Fig. 2 is a similar view of a modified from of the invention.

Fig. 3 is a front elevation of the bracket in the modified form.

Referring to the drawing by numerals of reference:

There is provided the usual base plate I preferably constructed at its inner periphery with a flange 2 which may be welded in place or formed in other preferred manner. Secured to the base plate by suitable means, for instance the rivets 3, is a traversing rack 4 having an angularly disposed end 5 spaced from the inner edge of the plate and providing rails or tracks 6 and I angularly disposed with relation to each other.

The side wall 8 of the turret has its lower edge located in the channel formed'between the inner 1 other objects in view,

periphery of the base plate I and the angularly act of March 3, 1883, as

disposed end 5 of the rack and secured to the wall in spaced relation are studs 9 (only one of which is shown) upon which are carried brackets l0. Encircling each stud and housed within its bracket is a bushing H having mounted thereon r rollers I2 upon which rollers is mounted a ring l3 contacting the track 6, the whole constituting an anti-friction roller to roll on the track 6. Upon the lower portion of each bracket I0 is carried a stud l4 encircled by an eccentric bushing l5 mounting rollers l6 and a ring H in contact with the track I, the whole constituting an anti-friction roller to roll on the track 1.

The eccentric bushing l5 may be rotated upon the stud I 4 to adjust the roller with respect to the track and clamped in adjusted position by means of a nut 22 threaded on the end of the stud.

The modified form shown in Fig. 2 is the same as that heretofore described except that the lower end of the bracket I8 is split at H) and drilled to receive a clamping bolt 20 which serves to clamp the eccentric stud 2! in place in the bracket. The eccentricity of the stud permits adjustment of the roller toward or away from the track I.

From the foregoing it will be evident that the rollers on the studs 9 bearing on the track 6 support the weight of the turret while the rollers on the studs It or 2| engaging the track I support the turret against lateral thrust and also against a force tending to lift the turret.

We claim:

In a roller bearing, a support, a stud fixed to the support and projecting from one side of the support, a bushing mounted on the stud, said bushing having a flange and an eccentric outer surface between the flange and the support, a nut on the fixed stud for clamping the bushing against the support to hold it in position of angular adjustment, rollers on the eccentric outer surface of the bushing and confined between the flange of the bushing and the support, and a wheel on the rollers confined between the flange of the bushing and the support.
